摘要： A control unit (41) controls an opening of an exhaust recirculation valve (6) according to a running condition of a diesel engine (1).

摘要： A basic target excess air factor tLAMBDA0 and a target fresh air intake amount tQac are set base upon the operation condition of an engine (30). A target excess air factor tLAMBDA is calculated by multiplying the ratio of a real fresh air intake amount rQac as detected by a sensor (16) and the target fresh air intake amount tQac by the basic target excess air factor tLAMBDA0. A fuel injector (9) is controlled so that the amount of fuel injected thereby converges to a target fuel injection amount tQf which corresponds to the target excess air factor tLAMBDA. It is possible to prevent variation of the output torque of the engine (30) accompanying a rich spike by this control, even if the basic target excess air factor tLAMBDA0 varies abruptly, since the fuel injection amount varies in correspondence to the variation of the real fresh air intake amount rQac.

摘要： A method for controlling an engine comprises establishing a torque correction coefficient (KA) to compensate for reducing effect of available engine torque in operating range of different excess air ratios (&lgr;) that are lower than a predetermined value (unity=1). An initial base desired in-cylinder air mass (tQacb) is determined based on a requested engine torque (tTe). A desired excess air ratio (t&lgr;) is determined. The initial base desired in-cylinder air mass (tQacb) is adjusted with at least the desired excess air ratio (t&lgr;) and the correction coefficient (KA) to generate a desired in-cylinder air mass (tQac). A desired injected fuel mass (tQf) is controlled based on the desired in-cylinder air mass (tQac) to deliver the requested engine torque (tTe) with the desired excess air ratio (t&lgr;) held accomplished.

摘要： An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, and an assist actuator controlled by a control unit. A first connecting member of the select lever and a second connecting member of the mode shift unit are relatively movable to a limit amount to each other and integrally movable beyond the limit amount with each other. The positions of the members are detected by an operating position sensor and an assist position sensor, respectively. The actuator is driven so that a difference between an operating position and an assist position may be reduced, but prohibited from driving when the difference is kept out of a permissible range for a predetermined period during rest of the actuator.
